Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the exploded view of Fig. 4 shows the basic composition of the structural parts in the utility model. As shown in FIG. 4 , 10 is a casing, 11 is a buckle groove, and the sealing ring 20 is fixed through the sealing groove on the battery 30 .

Referring to FIG. 4 and FIG. 5 , FIG. 5 is a cross-sectional view, that is, the detailed view C in FIG. 2 , and FIG. 5 shows the mating state of various structural components in which the battery 30 is installed in the casing 10 . It shows the structural form of the connection buckle of the battery and the casing of a portable phone device according to the embodiment of the present invention.

The battery buckle 40 and the spring 41 are fixed in the buckle groove 11 on the casing 10 . Fins 43 are formed on both sides of the battery buckle 40, and fin grooves 12 are formed at corresponding positions on both sides of the buckle groove 11 of the casing 10, and the fins 43 are installed in the fin grooves 12, so that the battery buckle 40 can move along the fin The sheet groove 12 moves up and down, the battery buckle 40 has an inner chamber 44, and there is a downward cylinder 42 on the inner surface of the inner chamber 44. The cylinder 42 is about half of the height of the inner chamber 44, and is located at the inner end of the inner chamber 44, so that the cylinder 42 is in the Below the bayonet pin 45 of the battery buckle 40 , to ensure that the spring force is consistent with the force direction of the bayonet pin 45 . The spring 41 is set on the cylinder 42, and the spring force will make the inner surface of the bayonet pin 45 of the battery buckle 40 be pressed against the inner surface of the battery groove 31, thereby locking the battery 30 and generating a pressing force on the sealing ring 20, So as to ensure the sealing requirements.

The spring force of the spring 41 should be selected appropriately, and should meet the requirements on the locking force of the battery 30, so as to achieve the pressing force on the sealing ring 20 and maintain an effective seal.

When installing the battery, first push the battery buckle 40 down to the limit position in the direction of the arrow shown in Figure 5, then put the battery 30 into the battery compartment 50 of the casing 1 and release the buckle 40, under the elastic force of the spring 41 Next, the inner surface of the bayonet pin 45 of the battery buckle 40 is tightly pressed against the inner surface of the battery groove 31, so that the battery buckle 40 can lock the casing 10 and the battery 30 tightly.

When the battery 30 needs to be removed, when the battery buckle 40 is pressed down along the direction shown by the arrow in Figure 5, the bayonet pin 45 of the battery buckle 40 will come out from the buckle groove 11 of the battery 30, and the battery 30 can be removed from the casing. 10 removed.

Figure 7 is a sectional view of the casing 1, and Figure 8 is an exploded view of the battery 30 and the sealing ring 20, as can be seen from Figures 8 and 10, the battery 30 includes a battery cell 36 and inner and outer casings 35, 34, and the battery cell 36 and The inner and outer casings 35, 34 are integrated into one body by ultrasonic welding. There are two small bosses 32 on the top of the battery case 34 , and it can be seen from FIG. 7 that there are two positioning grooves 51 at the corresponding positions on the top of the battery compartment 50 in the casing 10 to cooperate with it. The cross-sectional views of Fig. 6 and Fig. 7 show the cooperation between the two in the assembled state. Such cooperation between the boss 32 and the groove 51, together with the positioning and locking of the battery buckle 40, makes the battery 30 firmly fixed in the battery compartment 50, which not only ensures the reliability of assembly, but also strengthens the sealing and waterproofing of the whole machine sex.

Fig. 8 is an exploded view, and Fig. 10 and Fig. 11 are a sectional view and a partially enlarged view, and the two accompanying drawings show a waterproof structure such as a battery 30 part of a portable telephone device according to an embodiment of the present invention. As shown in FIG. 8 , there is an annular groove 33 around the battery inner casing 35 for fixing the silicone sealing ring 20 . As shown in FIG. 10 and FIG. 11 , in a natural state, the sealing ring 20 and the annular groove 33 adopt a clearance fit laterally; the sealing ring 20 adopts a tapered structure with a narrow bottom and a wide top to reserve space for the compression deformation of the sealing ring 20 ; In addition, the top of the sealing ring 20 is higher than the sealing annular groove 33 by a certain height, and the higher part is designed to be similar to a "mountain" structure with a high middle and low sides, and the height is about 0.5mm, which is conducive to the sealing and deformation of the sealing ring 20. , and can expand the sealing area and improve the sealing effect.

Fig. 12 is a sectional view, ie, detail view B in Fig. 2, showing the waterproof structure in a partially assembled state of a battery such as a portable telephone device according to an example of the present invention. As shown in Figure 12, the sealing ring 20 fixed in the sealing annular groove 33 adopts an interference fit with the contact surface of the casing 10. When the battery 30 and the sealing ring 20 are assembled into the casing 10, the top of the sealing ring 20 is subjected to pressure. Compression deformation makes it fill the gaps that may exist around the periphery, thereby forming a closed space in the inner area of the sealing ring 20, preventing liquids such as water and dust from entering the device or reaching the circuit through the connecting part of the battery 30 and the casing 10 The board effectively achieves the purpose of waterproof and dustproof. In addition, as shown in Figure 12, the annular groove 33 on the battery inner casing 35 protrudes outwards, and the casing groove 13 is designed to match it at the corresponding position of the casing 10, thereby further ensuring the deformation space of the silicone sealing ring 20 , enhancing the reliability and waterproof sealing of the casing 10 and the battery 30 .

The utility model provides a battery waterproof sealing structure, which includes a battery buckle 40 equipped with a spring 41, a boss 32 on the top of the battery case 34 and a matching positioning groove 51, which are used to firmly connect the battery 30 and the machine. The shell 10 is convenient for disassembly and assembly; it also includes a silicone sealing ring 20 and an annular groove 33 matched with it, which is arranged on the inner surface of the battery inner shell 35, and the casing in the casing 10 that matches the protruding annular groove 33 Groove 13, in the assembled state, the sealing ring 20 is compressed and deformed to fill the gap between the casing 10 and the battery 30, thereby effectively preventing water or similar liquids or dust from entering the interior of the casing 10 or the circuit board surface of the PCB 60 from the periphery of the battery 30 role.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model in other forms. Any skilled person who is familiar with this profession may use the technical content disclosed above to change or remodel it into an equivalent change. Equivalent embodiment. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present utility model still belong to the protection scope of the technical solution of the present utility model.
